PATENT JOSEPH WURZNER, OF CHICAGO, ILLINOIS, ASSIGNOR OF TWO-THIRDS OF HIS RIGHT TO JOSEPH MIEHLE AND FRANK SOHVVEINFURTH, OF

SAIME PLACE.

SPECIFICATION forming part of Letters Patent No. 226,144, dated March 30, 1880.

Application filed December 4, 1879.

To all whom it may concern Be it known that I, JOSEPH WURZNER, of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Automatic Fans and Ventilators, of which the following is a specification.

The purpose of my invention is to produce an automatic fan for use upon tables or in other places to prevent flies or other insects from alighting upon objects over which the fan is placed, and for use in sick-rooms or in other locations for fanning persons, which fan will have means for directing and controlling the blast of air, so as to produce a greater effeet. and will also serve the purpose of a ventilator by conducting fresh air into the room, and will at the same time be simple and cheap in construction and not liable to get' out of order.

My invention therein consists in the pecu' liar fan and the devices for controlling and directing the current of air; in the combination, with the same, of an elastic pipe-connection with the outside atmosphere; and, further, in the combination, with the fan, of the means for operating and regulating the same, all as fully hereinafter explained.

In the accompanying drawings, forming a part hereof, Figure 1 is a top view of the fan and ventilator; Fig. 2, a vertical cross-section of the same on the line on; Fig. 3, an end elevation of the same, and Fig. 4 a vertical longitudinal section on the line y. 3

Like letters denote corresponding parts in all the figures.

In the ends of horizontal arms a a of a suitable frame, A, is journaled the rock-spindle B of the oscillating or swinging fan 0, which projects downwardly from the under side of such spindle between such arms. A shield, D, is supported by such arms a a over the rock-spindle and the fan. This shield has a tubular cap or hub 11, with an open bottom, placed centrally over the rock-spindle, and having radial or diverging wings c, which extend downwardly and outwardly from the sides of such open bottom nearly or quite to a level with the bottom edge of the fan.

The fan, when the rock-spindle is moved, oscillates' back and forth between the wings c and causes a downward blast or current of air.

One end of the tubular cap I) is closed to the admission of air by the arm a, while at the other end of such cap the opposite arm (6 has perforations a, and is connected with a flexible air-pipe, E, which leads to the atmosphere.outside of the building. This fresh-air pipe can be connected with the cap I) at any other suitable point, and in summer time can be led through an ice or water box to cool the air.

The opposite end of the rock-spindle is extended through the arm a, and has a crankarm, (I, secured thereto, which crank-arm is connected by a pitman, 6, with a crank-wheel, f, which is revolved, through a train of gearing, by a spring, weight, or other suitable mo tive power.

'The end of the spindle B outside of the crank-arm d has a regulating pendulum-arm, 9, attached thereto, which is provided with a weight, h, adjustable upon the arm by means of a set-screw, so that the oscillation of the fan can be regulated and its speed increased or diminished, as desired.

The device is preferably made portable; but i it may be attached to a table, bed, chair, or other article of furniture, or it may be secured to the wall or hung from the ceiling.

The fan causes a downward blast or current of fresh air when in operation, which can be utilized, as before pointed out,.or for numerous other purposes.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The oscillating fan C,in combination with the shield 1), substantially as described and shown.

2. The combination, with the oscillating fan G and shield D, of the flexible air-pipe E, substantially as described. and shown.

3. The combination of the oscillating fan 0 and the shield D with the motor for operating the fan, substantially as described and are combined-an oscillating 'fan driven by a shown. motor, the shield with diverging wings, and 10 4. The combination of the oscillating fan the flexible fresh air pipe, substantially as set 0 and shield D with the motor for operating forth and shown.

5 the fan and the pendulum for regulating the JOSEPH WURZNER.
